the inner wall 9 of said pipe 4, ring 6 having its outer edge 10 projecting very slightly be-- yond the edge 11 of the pipe 4 and the inner This invention relates to improvements in stove pipes, and has for its object to provide means whereby the pipe may be locked in place in the chimney.

Another object of the invention is to provide an attachment for a stove pipe whereby the same may be securely lockedin the chimney.

.With the above and such other objects in view as may hereinafter more fully'appear,

I have invented the device illustrated in'the accompanying drawings, in \VhlCl'l'Z Figure 1 is a sectional elevational View of a chimney showing a stove. pipe locked thereto; Figure 2 is a sectional elevational view of a stove pipe embracing my invention;

Figure 3 is a view similarto Figure 1, showing the pipe unlocked for removal,

'Like reference characters indicate like partsfthroughout the specification and in the several views'in the drawings,f1nwh1ch 1 indicates a chimneyhaving a pipefopening I 2, through which one end-3 of a stove pipe 4 is adapted to project; My invention consists of the attachment 5 illustrated'in Figure 5, and which consists of a pair of'spaced apart ring bands 6 and 7 connected together by arms 8, the said rings snugly fitting against ring 7 is provided with a beveled outer wall surface 12 the knife edge 13 thereof projecting inwardly of said pipe. On the outside of said pipe 4 is-vprovided another wedge shaped ring 14 its knife edge 15 projecting in% the direction of the chimney 1 and being forced directly over the ring 7 whereby the wall 16 of the pipe 4 will be tightly-wedged between said rings and distorted thereby, negativing the possibility, of said rings becoming loosened and unseated relative to one another. The ring 14 isprovided with opposing ears 17 and 18 having apertures 19 Figure 6 is a section on line 6 6 of Figject, these wires provided with heads 23,3 whereby the wires are manipulated; said the pipe 4 'wires 21 and 22 projecting over through opening 2 and having the 1111181 terminals linked to the edges 23 W124 of a the lock members 25 and 26 hinged at 27 and 28 to the said projectingedgefllO of ring 6 in order that when said heads 23 are pulled upon drawing out the wires 21' and 22 the members 25 and 26 are operated to vertical POSltlOIl and engage the inner wall 29 of the chimney 1. Clamps 3O and-31 are provided on the outer ends of wires 21 and 22 whereby they may be held in the outermost positior to lock the members 25 and 26 in the vertical position whereby it will be'impossible o for the pipe 4 to becomejaccidentally detached from its chimneyl. As thering-lt seats directly the pipe collar 32 thesame will be held in place againstthewall 33.
